摘　　要：分别以碳纳米颗粒(CNPs)、碳纳米纤维(CNFs)和碳纳米管(CNTs)等纳米碳材料为填料,采用悬浮法制备了酚醛树脂(PF)/纳米碳材料复合保温材料。与PF相比,所制PF/纳米碳材料复合材料的力学性能和阻燃性能都有不同程度的提高,并且仍具有较好的保温性能。CNFs与CNTs在PF基体中的分散性较好,CNPs容易发生团聚。采用CNFs改性的PF/CNFs复合材料的综合性能最好,当w(CNFs)为10%时,PF/CNFs复合材料的拉伸强度为6.7MPa,悬臂梁缺口冲击强度为26.0 MPa,弯曲强度为9.8 MPa,线烧指数和质烧指数分别为38.8μm/s和32.6 mg/s,热导率约为0.030 W/(m·K)。A series of phenol-formaldehyde（PF）resin/carbon nanomaterial composite thermal insulation materials containing carbon nano-particles（CNPs）, carbon nano-fibers（CNFs） and carbon nano-tubes（CNTs） are prepared by suspension polymerization. All of these PF/carbon nanomaterials exhibit better mechanical and flame retardant properties than those of PF, and similar thermal insulation performance with PF. The dispersibility of CNTs and CNFs are better than CNPs due to the reunion phenomenon of CNPs. The PF/CNFs materials modified with CNFs show the best performance. The PF/CNFs materials with 10% content of CNFs possess 6.7 MPa of tensile strength, 26.0 MPa of Izod notched impact strength, 9.8 MPa of bending strength, 38.8 μm/s of liner change, 32.6 mg/s of mass change, and 0.030 W/（m·K）of thermal conductivity.
